Answer:

f(10) = -130

Step-by-step explanation:

f(x) = -x² - 3x

f(10) = -(10)² - 3(10)

f(10) = -100 - 30

f(10) = -130

Write the equation for the line whose slope is -1/4 and goes through the point (-2,6)​

Answers

Answer:

[tex]y = -\frac{1}{4} + \frac{11}{2}[/tex]

Step-by-step explanation:

use y = mx + b where:

y = y-coordinate = 6

m = slope = -1/4

x = x-coordinate = -2

b = y-intercept = what we're solving for to complete the equation

plug the values into the equation

[tex]6 = -\frac{1}{4}(-2) + b[/tex]               multiply [tex]-\frac{1}{4}[/tex] and 2

[tex]6 = \frac{1}{2} + b[/tex]                         subtract [tex]\frac{1}{2}[/tex] from both sides

[tex]b = \frac{11}{2}[/tex]

now we plug m and b into the equation and leave x and y as variables to get the final equation:

[tex]y = -\frac{1}{4} + \frac{11}{2}[/tex]

What would be the solution to the system of equations: y= -x + 4 y= 3x

Answers

Answer:

Step-by-step explanation:

The value of y is given in equation 2

Putting value of y = 3x in equation 1

Y = - x + 4

3x = - x + 4

Bringing like terms on one side

3x + x = 4

4x = 4

x = 4/4 = 1

Now putting value of x = 1 in equation 2

Y = 3x

Y = 3(1) = 3

Two years ago a man was five times as old as his son. Two years later his age will be eight more than three times as old as his son . Find there present age

Answers

Answer:

The age of man is 42 years and the age of his son is 10 years.

Answer: Father 42 and son 10

Let the age of the father is x years and that of the son is y years.

Then by the given question,

x-2=5(y-2)

or, x-5y=-10+2

or, x-5y=-8

or, x=5y-8

x+2=3(y+2)+8

or, x-3y=6+8-2

or, 5y-8-3y=12

or, 2y=12+8

or, y=20/2

or, y=10

then x=5y-8=50-8=42

Then, the age of father is 42 yrs. and the age of sun is 10 yrs.

a: b = 1:7
a:c= 4:1
How many times bigger is b than c?

Answers

Answer:

a / b = 1/7

b = a x 7

a / c = 4 /1

a = c x 4

b = a x 7

= c x 4 x 7

= c x 28

b is 28 times bigger than c

b is 28 times bigger than c. The conclusion is obtained by rearranging the equations.

What exactly are ratio and proportion?

A ratio is an ordered pair of integers a and b, expressed as a/b, where b cannot be zero. A proportion is an equation that sets two ratios equal to each other.

The given ratio;

a: b = 1:7

a:c= 4:1

Rearrange the given ratio we obtained;

b = a × 7

a = c × 4

Put the value of a in b get;

b= c × 4 × 7

Hence, b is 28 times bigger than c.

Parallelogram A B C D is shown. The length of A B is (9 x minus 14) inches and the length of D C is (3 x + 4) inches. In parallelogram ABCD, what is DC? 3 in. 9 in. 13 in. 19 in.

Answers

Given:

In a parallelogram ABCD, AB=(9x-14) inches and DC=(3x+4) inches.

To find:

The measure of DC.

Solution:

We know that opposite sides of a parallelogram are equal.

In the parallelogram ABCD, AB and DC are opposite sides. So,

[tex]AB=DC[/tex]

[tex]9x-14=3x+4[/tex]

[tex]9x-3x=14+4[/tex]

[tex]6x=18[/tex]

Divide both sides by 6.

[tex]x=\dfrac{18}{6}[/tex]

[tex]x=3[/tex]

Now,

[tex]DC=3x+4[/tex] inches

[tex]DC=3(3)+4[/tex] inches

[tex]DC=9+4[/tex] inches

[tex]DC=13[/tex] inches

The measure of DC is 13 in.

Therefore, the correct option is C.

Answer:

Step-by-step explanation:

Anna&katie together have $60.Anna has $9 more than twice Katie's amount how much money does each have? Write a system and use substitution to solve

Answers

Answer:

Ana had $17 and Katie had $43.

Step-by-step explanation:

Since Ana and Katie together have $60, you can express this as follows:

x+y=60, where:

x is the amount that Ana has

y is the amount that Katie has

Also, Anna has $9 more than twice Katie's amount, which can be expressed as:

x=2y+9

The system is:

x+y=60 (1)

x=2y+9 (2)

Now, you can replace (2) in (1) and solve for y:

2y+9+y=60

3y=60-9

3y=51

y=51/3

y=17

Finally, you can replace the value of y in (2) to find x:

x=2(17)+9

y=34+9

y=43

According to this, the answer is that Ana had $17 and Katie had $43.
